Instrument Agents: AI Systems That Control Lab Equipment

An LLM that can answer questions about lab procedures is useful. An LLM that can execute those procedures through actual equipment is transformative—and significantly more complex to build safely.

Instrument Agents are AI systems that bridge the gap between natural language understanding and physical laboratory operations. They don’t just generate protocols; they orchestrate equipment, monitor execution, and adapt to real-world conditions.

This post explores the architectural patterns that make instrument agents work, with particular attention to the unique constraints of laboratory automation.

What Is an Instrument Agent?

An instrument agent is an AI system that can:

Capability	Description	Example
Understand	Parse high-level goals	”Prepare samples for ELISA”
Plan	Decompose into operations	Transfer → Incubate → Wash → Read
Execute	Call instrument APIs	pipette.transfer(...)
Observe	Monitor results and state	Check volumes, read measurements
Adapt	Modify plan based on feedback	Retry failed step, adjust parameters

The key difference from simple LLM applications: the agent operates in a feedback loop with the physical world.

Agent Architecture Patterns

Several architectural patterns have emerged for building AI agents. Each has different tradeoffs for laboratory applications.

Pattern 1: ReAct (Reasoning + Acting)

The ReAct pattern interleaves reasoning and action in a single loop:

Thought: I need to transfer samples from the source plate to the destination plate.
         The user requested 50µL per well.
Action: pipette_transfer(source="plate_1:A1-A6", dest="plate_2:A1-A6", volume=50)
Observation: Transfer complete. 6 wells transferred, total volume 300µL.

Thought: Transfer successful. Now I need to add reagent.
Action: pipette_transfer(source="reagent:A1", dest="plate_2:A1-A6", volume=25)
Observation: Transfer complete. Reagent added to 6 wells.

Thought: Samples prepared. Starting incubation.
Action: incubator_start(plate="plate_2", temp=37, duration=30)
Observation: Incubation started. ETA: 30 minutes.

Implementation:

class ReActAgent:
    def __init__(self, llm, tools: dict):
        self.llm = llm
        self.tools = tools
        self.max_iterations = 20

    def run(self, goal: str) -> AgentResult:
        history = []

        for i in range(self.max_iterations):
            # Generate thought and action
            prompt = self.build_prompt(goal, history)
            response = self.llm.generate(prompt)

            thought, action = self.parse_response(response)
            history.append({"thought": thought, "action": action})

            # Check for completion
            if action["type"] == "finish":
                return AgentResult(success=True, history=history)

            # Execute action
            try:
                observation = self.execute_action(action)
                history.append({"observation": observation})
            except ToolError as e:
                history.append({"error": str(e)})

        return AgentResult(success=False, reason="max_iterations", history=history)

    def execute_action(self, action: dict) -> str:
        tool_name = action["tool"]
        tool_args = action["args"]

        if tool_name not in self.tools:
            raise ToolError(f"Unknown tool: {tool_name}")

        return self.tools[tool_name].execute(**tool_args)

Pros:

• Simple, transparent reasoning
• Easy to debug and understand
• Works well for straightforward tasks

Cons:

• Can get stuck in loops
• Limited planning horizon
• Each step requires LLM call (latency)

Pattern 2: Plan-and-Execute

Separate planning from execution for better efficiency:

Phase	Components	Output
Planning	Goal → Planner LLM	Action Plan (all steps)
Execution	Executor → Tools	Step-by-step results
Replanning	Check Progress → Replan if needed	Updated plan

Flow: Goal → Plan all steps upfront → Execute sequentially → Replan on failure

Implementation:

class PlanAndExecuteAgent:
    def __init__(self, planner_llm, executor_llm, tools: dict):
        self.planner = planner_llm
        self.executor = executor_llm
        self.tools = tools

    def run(self, goal: str) -> AgentResult:
        # Phase 1: Generate plan
        plan = self.generate_plan(goal)

        # Phase 2: Execute plan
        results = []
        for step in plan["steps"]:
            result = self.execute_step(step)
            results.append(result)

            # Check if replanning needed
            if result["status"] == "failed" or self.needs_replanning(results):
                plan = self.replan(goal, plan, results)

        return AgentResult(success=True, plan=plan, results=results)

    def generate_plan(self, goal: str) -> dict:
        prompt = f"""
        Create a step-by-step plan to achieve this goal:
        {goal}

        Available tools:
        {self.format_tools()}

        Output a JSON plan with numbered steps.
        """

        response = self.planner.generate(prompt)
        return json.loads(response)

    def execute_step(self, step: dict) -> dict:
        tool = self.tools[step["tool"]]
        try:
            result = tool.execute(**step["args"])
            return {"status": "success", "result": result}
        except Exception as e:
            return {"status": "failed", "error": str(e)}

Pros:

• More efficient (fewer LLM calls)
• Better for complex, multi-step tasks
• Easier to review plan before execution

Cons:

• Less adaptive to unexpected situations
• Replanning adds complexity
• Initial plan may miss edge cases

Pattern 3: Hierarchical Agents

For complex laboratory workflows, use a hierarchy of specialized agents:

Level	Agent	Tools	Responsibility
Orchestrator	Master Controller	Delegates to specialists	Task decomposition, coordination
Specialist	Sample Prep Agent	Pipette	Dilutions, transfers, aliquoting
Specialist	Assay Agent	Pipette, Reader, Washer	Protocol execution
Specialist	Analysis Agent	Imager, Reader	Data collection, QC

Implementation:

class OrchestratorAgent:
    def __init__(self, specialists: dict[str, Agent]):
        self.specialists = specialists
        self.llm = create_llm("orchestrator")

    def run(self, goal: str) -> AgentResult:
        # Decompose goal into sub-tasks
        subtasks = self.decompose(goal)

        results = []
        for task in subtasks:
            # Route to appropriate specialist
            specialist = self.route_task(task)
            result = specialist.run(task["description"])
            results.append(result)

            # Check dependencies and adjust
            if not result.success:
                return self.handle_failure(task, results)

        return AgentResult(success=True, subtask_results=results)

    def decompose(self, goal: str) -> list[dict]:
        prompt = f"""
        Break down this laboratory goal into sub-tasks:
        {goal}

        Available specialists:
        - sample_prep: Sample preparation, dilutions, transfers
        - assay: Running assays, incubations, washes
        - analysis: Reading plates, imaging, data analysis

        Return JSON list of tasks with assigned specialist.
        """

        response = self.llm.generate(prompt)
        return json.loads(response)

    def route_task(self, task: dict) -> Agent:
        return self.specialists[task["specialist"]]


class SamplePrepAgent(Agent):
    """Specialist for sample preparation"""

    def __init__(self, tools: dict):
        self.tools = tools
        self.llm = create_llm("sample_prep")

    def run(self, task: str) -> AgentResult:
        # Specialized logic for sample preparation
        plan = self.plan_sample_prep(task)
        return self.execute_plan(plan)

Pros:

• Scales to complex workflows
• Each agent can be specialized and optimized
• Clear separation of concerns

Cons:

• More complex to build and maintain
• Communication overhead between agents
• Harder to debug end-to-end

Pattern Comparison

Pattern	Best For	Complexity	Latency
ReAct	Simple, interactive tasks	Low	High (many LLM calls)
Plan-Execute	Well-defined multi-step tasks	Medium	Medium
Hierarchical	Complex workflows with specialists	High	Low (parallel execution)

Tool Abstraction Layer

The agent’s effectiveness depends on how well its tools are designed. For laboratory instruments, this requires careful abstraction.

Tool Interface Design

Each tool should have a clear, consistent interface:

from abc import ABC, abstractmethod
from dataclasses import dataclass

@dataclass
class ToolResult:
    success: bool
    data: dict
    error: str | None = None
    duration_seconds: float = 0

class InstrumentTool(ABC):
    """Base class for instrument tools"""

    @property
    @abstractmethod
    def name(self) -> str:
        """Tool name for LLM reference"""
        pass

    @property
    @abstractmethod
    def description(self) -> str:
        """Human-readable description"""
        pass

    @property
    @abstractmethod
    def parameters(self) -> dict:
        """JSON Schema for parameters"""
        pass

    @abstractmethod
    def execute(self, **kwargs) -> ToolResult:
        """Execute the tool operation"""
        pass

    @abstractmethod
    def validate_params(self, **kwargs) -> list[str]:
        """Validate parameters before execution"""
        pass

    def to_schema(self) -> dict:
        """Generate schema for LLM consumption"""
        return {
            "name": self.name,
            "description": self.description,
            "parameters": self.parameters
        }

Example: Pipette Tool

class PipetteTool(InstrumentTool):
    """Tool for liquid handling operations"""

    def __init__(self, pipette_driver: PipetteDriver):
        self.driver = pipette_driver

    @property

        return """Transfer liquid between locations.
        Supports single transfers, multi-dispense, and mixing.

                    },
                    "description": "Optional mixing after dispense"
                }
            }
        }

    def validate_params(self, **kwargs) -> list[str]:
        errors = []

        volume = kwargs.get("volume_ul", 0)
        if volume < 1 or volume > 1000:

        return errors

    def execute(self, **kwargs) -> ToolResult:
        # Validate first
        errors = self.validate_params(**kwargs)
        if errors:
            return ToolResult(success=False, data={}, error="; ".join(errors))

        try:
            # Parse locations
            source = self.parse_location(kwargs["source"])
            destinations = self.parse_location(kwargs["destination"])
            volume = kwargs["volume_ul"]

            # Execute transfer
            start_time = time.time()

            self.driver.aspirate(source, volume)

            for dest in destinations:
                self.driver.dispense(dest, volume / len(destinations))

                if kwargs.get("mix_after"):
                    mix = kwargs["mix_after"]
                    self.driver.mix(dest, mix["cycles"], mix.get("volume_ul", volume/2))

            )

        except PipetteError as e:
            return ToolResult(success=False, data={}, error=str(e))

Tool Registry

Manage available tools through a registry:

class ToolRegistry:
    """Central registry for instrument tools"""

    def __init__(self):
        self._tools: dict[str, InstrumentTool] = {}

    def register(self, tool: InstrumentTool):
        self._tools[tool.name] = tool

    def get(self, name: str) -> InstrumentTool:
        if name not in self._tools:
            raise ToolNotFoundError(f"Tool '{name}' not registered")
        return self._tools[name]

    def list_tools(self) -> list[dict]:
        return [tool.to_schema() for tool in self._tools.values()]

    def execute(self, name: str, **kwargs) -> ToolResult:
        tool = self.get(name)
        return tool.execute(**kwargs)


# Usage
registry = ToolRegistry()
registry.register(PipetteTool(pipette_driver))
registry.register(PlateReaderTool(reader_driver))
registry.register(IncubatorTool(incubator_driver))

# Pass to agent
agent = ReActAgent(llm=llm, tools=registry)

Abstraction Levels

Design tools at the right abstraction level:

Level	Examples	Agent Sees?	Tradeoff
High (Domain)	run_elisa_assay(), prepare_serial_dilution()	No	Less flexible, hides complexity
Mid (Workflow)	transfer_liquid(), incubate_plate(), read_plate()	Yes	Right balance for most agents
Low (Hardware)	aspirate(), dispense(), move_arm()	No	Too many steps, error-prone

Recommendation: Expose mid-level tools to the agent. High-level tools reduce flexibility; low-level tools require too many steps.

Safety and Control Boundaries

Instrument agents operate in the physical world. Errors can damage equipment, waste expensive reagents, or compromise experiments. Safety must be built into the architecture.

Permission Model

Define what the agent can and cannot do:

@dataclass
class Permission:
    tool: str
    allowed_operations: list[str]
    constraints: dict

class PermissionManager:
    def __init__(self, permissions: list[Permission]):
        self.permissions = {p.tool: p for p in permissions}

    def check(self, tool: str, operation: str, params: dict) -> tuple[bool, str]:
        if tool not in self.permissions:
            return False, f"Tool '{tool}' not permitted"

        perm = self.permissions[tool]

        if operation not in perm.allowed_operations:
            return False, f"Operation '{operation}' not allowed for {tool}"

        for key, constraint in perm.constraints.items():
            if key in params:
                if not self.check_constraint(params[key], constraint):
                    return False, f"Parameter '{key}' violates constraint: {constraint}"

        return True, "OK"


# Example permission configuration
AGENT_PERMISSIONS = [
    Permission(
        tool="pipette_transfer",
        allowed_operations=["transfer", "mix"],
        constraints={
            "volume_ul": {"max": 200},  # Limit transfer volume
            "destination": {"pattern": r"^plate_[12]:.*"}  # Only specific plates
        }
    ),
    Permission(
        tool="incubator",
        allowed_operations=["start", "check_status"],
        constraints={
            "temperature_c": {"min": 20, "max": 40},  # Safe temperature range
            "duration_min": {"max": 120}  # Max 2 hours
        }
    ),
    # Note: No permission for "plate_shaker" - agent cannot use it
]

Action Validation Pipeline

Every action goes through validation before execution:

class SafetyValidator:
    def __init__(self, permission_manager: PermissionManager, rules: list):
        self.permissions = permission_manager
        self.rules = rules

    def validate(self, action: dict, context: AgentContext) -> ValidationResult:
        errors = []
        warnings = []

        # Check permissions
        allowed, reason = self.permissions.check(
            action["tool"],
            action.get("operation", "execute"),
            action["params"]
        )
        if not allowed:
            errors.append(f"Permission denied: {reason}")

        # Check safety rules
        for rule in self.rules:
            result = rule.check(action, context)
            if result.level == "error":
                errors.append(result.message)
            elif result.level == "warning":
                warnings.append(result.message)

        return ValidationResult(
            valid=len(errors) == 0,
            errors=errors,
            warnings=warnings
        )


# Example safety rules
class MaxActionsPerMinuteRule:
    """Prevent runaway agent behavior"""

    def __init__(self, max_actions: int = 10):
        self.max_actions = max_actions

    def check(self, action: dict, context: AgentContext) -> RuleResult:
        recent_actions = context.get_actions_in_window(seconds=60)
        if len(recent_actions) >= self.max_actions:
            return RuleResult(
                level="error",
                message=f"Rate limit: {self.max_actions} actions/minute exceeded"
            )
        return RuleResult(level="ok")


class VolumeConsistencyRule:
    """Ensure volumes are consistent with well capacity"""

    def check(self, action: dict, context: AgentContext) -> RuleResult:
        if action["tool"] != "pipette_transfer":
            return RuleResult(level="ok")

        dest = action["params"]["destination"]
        volume = action["params"]["volume_ul"]
        current = context.get_well_volume(dest)
        capacity = context.get_well_capacity(dest)

        if current + volume > capacity:
            return RuleResult(
                level="error",
                message=f"Volume overflow: {dest} would have {current + volume}µL (capacity: {capacity}µL)"
            )
        return RuleResult(level="ok")

Human-in-the-Loop Controls

For critical operations, require human approval:

class ApprovalRequired:
    """Decorator for actions requiring human approval"""

    HIGH_RISK_TOOLS = ["waste_disposal", "uv_sterilization", "centrifuge"]
    VOLUME_THRESHOLD = 500  # µL

    @classmethod
    def needs_approval(cls, action: dict) -> tuple[bool, str]:
        # High-risk tools always need approval
        if action["tool"] in cls.HIGH_RISK_TOOLS:
            return True, f"High-risk operation: {action['tool']}"

        # Large volumes need approval
        if action.get("params", {}).get("volume_ul", 0) > cls.VOLUME_THRESHOLD:
            return True, f"Large volume transfer: {action['params']['volume_ul']}µL"

        # First action in a new session
        # (paranoia check for runaway agents)

        return False, ""


class ApprovalGate:
    """Gate that pauses execution for human approval"""

    def __init__(self, approval_ui: ApprovalInterface):
        self.ui = approval_ui

    async def request_approval(self, action: dict, reason: str) -> bool:
        approval_request = {
            "action": action,
            "reason": reason,
            "timestamp": datetime.now(),
            "timeout_seconds": 300  # 5 minute timeout
        }

        self.ui.show_approval_request(approval_request)

        try:
            result = await asyncio.wait_for(
                self.ui.wait_for_response(),
                timeout=300
            )
            return result.approved
        except asyncio.TimeoutError:
            return False  # Default deny on timeout

Emergency Stop

Always provide a way to halt the agent:

class EmergencyStop:
    """Global emergency stop for agent operations"""

    def __init__(self):
        self._stopped = False
        self._stop_reason = None

    def stop(self, reason: str = "Manual stop"):
        self._stopped = True
        self._stop_reason = reason

State Management

Agents need to track the state of the laboratory environment:

@dataclass
class LabwareState:
    labware_id: str
    labware_type: str
    location: str
    wells: dict[str, WellState]

@dataclass
class WellState:
    volume_ul: float
    contents: list[str]  # List of reagent/sample names
    last_modified: datetime

class LabState:
    """Tracks current state of laboratory environment"""

    def __init__(self):
        self.labware: dict[str, LabwareState] = {}
        self.equipment_status: dict[str, str] = {}
        self.history: list[StateChange] = []

    def update_well(self, labware_id: str, well: str,
                    volume_delta: float, content: str | None = None):
        state = self.labware[labware_id].wells[well]
        state.volume_ul += volume_delta
        if content:
            state.contents.append(content)
        state.last_modified = datetime.now()

        self.history.append(StateChange(
            timestamp=datetime.now(),
            labware=labware_id,
            well=well,
            change_type="volume",
            old_value=state.volume_ul - volume_delta,
            new_value=state.volume_ul
        ))

    def get_well_volume(self, location: str) -> float:
        labware_id, well = self.parse_location(location)
        return self.labware[labware_id].wells[well].volume_ul

    def snapshot(self) -> dict:
        """Create a serializable snapshot for LLM context"""
        return {
            "labware": {
                lid: {
                    "type": lw.labware_type,
                    "location": lw.location,
                    "wells_summary": self.summarize_wells(lw.wells)
                }
                for lid, lw in self.labware.items()
            },
            "equipment": self.equipment_status
        }

Providing State to the Agent

Include relevant state in the agent’s context:

def build_agent_context(lab_state: LabState, goal: str) -> str:
    return f"""
## Current Laboratory State

### Equipment Status
{format_equipment_status(lab_state.equipment_status)}

### Labware
{format_labware_summary(lab_state.labware)}

### Recent Actions
{format_recent_history(lab_state.history[-10:])}

## Goal
{goal}

## Available Tools
{format_tools(tool_registry.list_tools())}

Error Handling and Recovery

Laboratory operations fail. Good agents handle failures gracefully.

Error Categories

Category	Examples	Recovery Strategy
Transient	Timeout, temporary sensor error	Retry with backoff
Recoverable	Tip pickup failed, position error	Specific recovery action
Fatal	Hardware fault, safety violation	Stop and alert
Logical	Invalid parameters, constraint violation	Re-plan

Recovery Strategies

class ErrorRecoveryHandler:
    def __init__(self, agent: Agent):
        self.agent = agent
        self.recovery_strategies = {
            "tip_pickup_failed": self.recover_tip_pickup,
            "position_error": self.recover_position,
            "timeout": self.retry_with_backoff,
            "volume_error": self.adjust_and_retry,
        }

    def handle(self, error: ToolError, context: AgentContext) -> RecoveryResult:
        if error.fatal:
            return RecoveryResult(action="stop", reason=str(error))

        strategy = self.recovery_strategies.get(error.code)
        if strategy:
            return strategy(error, context)

        # Unknown error - ask agent to decide
        return self.ask_agent_for_recovery(error, context)

    def recover_tip_pickup(self, error: ToolError, context: AgentContext):
        # Try alternative tip rack
        alt_tips = context.find_available_tips()
        if alt_tips:
            return RecoveryResult(
                action="retry",
                modifications={"tip_rack": alt_tips[0]}
            )
        return RecoveryResult(action="stop", reason="No tips available")

    def retry_with_backoff(self, error: ToolError, context: AgentContext):
        attempts = context.get_retry_count(error.action_id)
        if attempts < 3:
            delay = 2 ** attempts  # Exponential backoff
            return RecoveryResult(
                action="retry",
                delay_seconds=delay
            )
        return RecoveryResult(action="escalate", reason="Max retries exceeded")

    def ask_agent_for_recovery(self, error: ToolError, context: AgentContext):
        """Let the agent reason about recovery"""
        prompt = f"""
        An error occurred during execution:
        Error: {error.message}

        Current state: {context.snapshot()}

        What should we do?
        Options:
        1. Retry the action (possibly with modifications)
        2. Skip and continue with next step
        3. Stop execution and alert operator
        4. Execute a recovery procedure

        Explain your reasoning and choose an action.

        response = self.agent.llm.generate(prompt)
        return self.parse_recovery_decision(response)

Practical Architecture

Putting it together for a real system:

Layer	Components	Role
User Interface	Input, Status, Approval UI	Human interaction, oversight
Agent Layer	Orchestrator + Specialists	Goal decomposition, execution logic
Safety Layer	Permission Manager, Validator, E-Stop	Guardrails, approval gates
Tool Layer	Tool Registry + Individual Tools	Abstraction over hardware
Hardware Layer	Instrument Drivers	Direct hardware communication
State	Lab State, Audit Log	Tracking, compliance

Key Connections:

• User → Orchestrator → Specialists → Permission Check → Tool Registry → Hardware
• Emergency Stop can halt Tool Registry at any time
• All tool executions logged to Audit Log

Model Selection

Component	Recommended Model	Reasoning
Orchestrator	Mistral-7B / Llama3-8B	Needs reasoning for task decomposition
Specialist Agents	Phi-3 / Qwen3-3B	Focused domain, can be smaller
Tool Selection	Qwen3-0.6B	Simple classification task
Error Recovery	Same as orchestrator	Needs reasoning

Considerations for Adoption

Start with Constrained Domains

Don’t try to build a general-purpose lab agent. Start with:

• Single workflow type (e.g., just ELISA)
• Limited tool set (e.g., pipette + reader only)
• Strict permissions (narrow what agent can do)

Build Trust Incrementally

1. Phase 1: Agent suggests, human executes
2. Phase 2: Agent executes simple steps, human approves each
3. Phase 3: Agent executes routine workflows, human approves batch
4. Phase 4: Agent executes autonomously with oversight

Monitor and Audit

Every agent action should be logged:

@dataclass
class AgentAuditEntry:
    timestamp: datetime
    session_id: str
    agent_id: str
    action_type: str  # "plan", "execute", "observe", "decide"
    content: dict
    reasoning: str | None
    result: dict | None
    user_approvals: list[str]

Regulatory Implications

For GxP environments:

• The agent system itself needs validation
• Agent decisions affecting quality need documentation
• Human oversight requirements may be mandated
• Audit trails must be complete and tamper-evident

Closing Thoughts

Instrument agents represent the frontier of laboratory automation—systems that can understand goals, plan operations, and adapt to real-world conditions. The technology is advancing rapidly, with frameworks like LangChain, AutoGen, and domain-specific tools like ROSA making implementation more accessible.

But capability without safety is dangerous in laboratory environments. The architectural patterns that matter most aren’t about making agents smarter—they’re about making them controllable, predictable, and transparent.

Build agents that humans can trust: start narrow, validate thoroughly, maintain oversight, and expand gradually as confidence grows.

The field of AI agents is evolving rapidly. Specific frameworks and models will change, but the principles of safety-first design, clear tool abstractions, and human oversight will remain essential.
